Starting from a reference in this answer about elastic (non-rigid) transforms between images, I am wondering whether OpenCV supports such transforms.
So, given an image, some landmarks in it, and a new set of landmarks, it is a way to transform the image so that the old landmarks move to the new set? By elastic transform, I mean it should not be a simple homography, but a more flexible (locally adaptive) algorithm. The idea would be to create a map between the original and the destination, in such a way that the old image looks "stretched" or "squizzed"
I know algorithms that do it, and how it works, I am just curious whether such functions are available in OpenCV.
